Product Description

At present, the fourth generation bipolar output technology based on full bridge inverter has been widely adopted by 50% of domestic micro arc oxidation equipment manufacturers. However, in large-scale production, such as automobile parts and 3C shell, most of the time of micro arc oxidation process is micro arc discharge stage, and the current density is between 2A / DM2 and 10A / DM2. Although the film treatment time is very short, the single line efficiency is low and the installed capacity is too large, which restricts the use of mass production. For example, for the automobile hub production line, the single line installed capacity exceeds 500kW, but the processing quantity per hour is only 25, which is far from meeting the needs of the previous process. In addition, for the micro arc oxidation equipment of most domestic manufacturers, the compactness of the prepared film is not enough, and the anti-corrosion capacity is between 800-1000 hours, which is far less than the requirements of  industry, special environment and preparation of new materials. Therefore, our company has developed the sixth generation customized micro arc oxidation power supply according to the technical background of  power supply for many years.

1. Low energy consumption ultra narrow pulse micro arc oxidation equipment

The domestic conventional manufacturers' micro arc power supply has only 10-80% duty cycle, resulting in high power consumption and low discharge accuracy. The power supply is as low as 2%,

The advanced nature of the power supply:

1. Have all accuracy and process parameter indexes of the fourth generation power supply

2. It has the advantages of parallel connection of the fifth generation power supply, low power consumption and low failure rate.

3. It is especially suitable for magnesium alloy coloring processing and complex cavity processing, without slag and burning loss.

4. It can be used as conductive micro arc oxidation.



2. High frequency and high voltage pulse micro arc oxidation equipment

The micro arc power supply of domestic conventional manufacturers has only the rated voltage of 750V, which leads to insufficient density of micro arc oxide film and low withstand voltage.

The power supply voltage can reach 1500V, and the frequency can be advanced to 10KHZ according to customer needs.

1. Have all accuracy and process parameter indexes of the fourth generation power supply

2. The power supply cannot be connected in parallel,

3. Especially suitable for voltage resistant film and high corrosion resistant film (aluminum alloy: neutral salt spray ≥ 2000h, scratch salt spray ≥ 800H, hardness > 600hv, breakdown voltage > 1200V)



3. Ultra high power micro arc oxidation equipment

Due to the capacity limitation of IGBT, the micro arc power supply of domestic conventional manufacturers is generally up to 300kW, which leads to low efficiency when making large quantities of products.

And the power supply can achieve the maximum 800KW, which is advanced.

1. Have all accuracy and process parameter indexes of the fourth generation power supply

2. The power supply is in parallel mode, each 100A,

3. It is especially suitable for large quantities of products



4. Ultra precision micro arc oxidation equipment

Due to the influence of electrical component accuracy and acquisition feedback rate, the film thickness of micro arc power supply of conventional domestic manufacturers is generally 5-100 microns.

The power supply can achieve 0.2-5 micron, and the power is advanced.

1. The display accuracy and acquisition accuracy are 0.1A and 0.1V, the duty cycle is 2-10%, the voltage is 0-1000v, and the maximum average current is 1-5a.

2. The power supply is in normal mode with constant current,

3. Preparation of new materials especially suitable for micro nano products
